摘要： PURPOSE: To obtain a extrafine solder coating wire at low cost and with good efficiency by making a base wire with the extrusion coating of a solder on a core wire and by performing a wire drawing work without the heat treatment of this base wire.
CONSTITUTION: The solder coated wire 5 consisting of a core wire 2 and the solder 1A coating the core wire 2 is obtained by passing the core wire 2 through a die 4 with applying a tension on the core wire 2 with preheating and pressing a solder billet 1. A wire drawing is performed with more than 85% reduction with this solder coated wire 5 as the base wire without subjecting to a heat treatment on the way. With this method the extrafine solder coated wire of high strength having sufficient hardening work is obtd.

摘要： PURPOSE:To obtain highly efficiently a zinc coated brass wire with thick thickness and the prescribed size and strength characteristics, by adopting a base wire extrusion and drawing system as a manufacture of a titled composite electrode wire of zinc coated brass wire. CONSTITUTION:A zinc billet 3 is heated by using an extruder 1 and, on the other hand, a brass wire 2 is preheated to apply a tension forward to the wire 2 while lowering a stem 6 under pressure, thereby passing the wire 2 through a nipple 5 and a die 4 to extrude a composite base wire 7. Next, the base wire 7 is continuously drawn through several tens of passes, and an extremely fine wire 8 is obtained by drawing it at a reduction ratio of >=90% in total.
摘要翻译：目的：通过采用基线挤压拉丝系统作为镀锌黄铜丝的复合电极丝的制造，高效地获得厚度厚，规格和强度特性的镀锌黄铜丝。构成：通过使用挤出机1对锌钢坯3进行加热，另一方面，对黄铜线材2进行预热，以在压力下降下杆6的同时向线材2施加张力，由此使线材2通过接头5和模具4挤出复合基线7.接下来，基线7被连续地拉伸数十次，并且通过以> = 90％的压缩比拉伸极细丝8 总。
